I think this would be the best to start - due to the fact that I need
bitbanging for FPGA flashing, too.

@Prafulla:
in kirkwood/cpu.c
there are 2 functions:
kw_config_gpio()
kw_config_mpp()
If I implement additional functions like
kw_gpio_direction(int gpio, enum direction)
kw_gpio_set(int gpio, int value)
int value kw_gpio_get(int gpio)
If the functions are implemented in cpu.c are they accessible from cmd_xxx.c
functions?
Would this be ok to get it mainline or should there be an special driver for
gpio access?
Sorry for my newbie questions :)
